You want to read about the Javascript DOM.

Start with the following: http://www.w3schools.com/htmldom/dom_obj_form.asp

Specifically you're looking to manipulate document.checks.inputbox.value

You can use javascript to set the value of that element to p.

<script type="text/javascript">
    document.getElementById("Text1").value = p;
</script>

Solution 3

document.getElementById('Text1').value = p;

Solution 4

Using Javascript:

<script type="text/javascript">
    document.getElementById("Text1").value = p;
</script>

Using jQuery:

<script type="text/javascript">
    $("#Text1").val(p);
</script>
